Bony fish are fish that have a skeleton made of bone. They also have teeth that are fixed onto the upper jaw. They have a swim bladder (an air filled sac that helps them with buoyancy) that opens into the gullet. Bony fish do not have to swim to breathe (to push water through the gills).

Subclass Actinopterygii (Ray-finned fish) - The fins of these fish have jointed, bony rays that support them. These fish have large eyes and no internal nostrils. They have a swim bladder (an air filled sac that helps them with buoyancy) that opens into the gullet. Most bony fish are in this subclass. Examples: herring, eels, sturgeon, salmon, lantern fish, milk fish, garpikes, carp, catfish, toadfish, anglers, cod, flying fish, John Dory, sticklebacks, seahorses, scorpionfish, perch, flatfish, triggerfish, pufferfish.

DinichthysDunkleosteus was a extinct, armored fish from the family Dinichthys. This extinct family of fishes lived during the Late Devonian period, about 400 million years ago.

EelsInformation and printouts on these primitive fish that go through metamorphosis.

In addition to printing the animals, you can copy a printout (click here for instructions) and paste it into a painting program (like Paint) and color the animal there. (Thanks to Grace P. from Thorngrove School for this great idea.)
